2.10. RPM correction map

In the “RPM correction" tab, an additional correction map is displayed to supplement the multiplier map.

Fig. 23

The view on the RPM correction map

The RPM correction map forms a plane. One axis of the plane represents the petrol injection time [ms], while the other represents engine revolutions [rpm]. The map makes it possible to calibrate the multiplier depending on engine revolutions. This is shown In Fig.12. It is possible to enrich/weaken the mixture for a defined petrol injection time and revolutions.

In order to calibrate the multiplier, the area which is to be calibrated must be selected by moving the mouse with the left button pressed over this area.

Another method is to press the SHIFT key and, while holding it, to select the appropriate area by pressing arrow keys:

← Left arrow

↑ Up arrow

→ Right arrow

↓ Down arrow

Having marked the area which is to be calibrated, specified actions can be performed by using the combination of the CTRL key and one of the keys below:

↑ Arrow up (higher calibration/richer mixture)

↓ Arrow down (lower calibration/leaner mixture)

Pressing the SHIFT key in the course of the multiplier calibration will multiply the required step by 10.

The “3D” tab seen on the right side of the RPM correction map windows allows activation of a 3D view. Return to the classic two-dimensional view is made through the “2D” tab.
